I'm doing decomposition of hydrogen peroxide and was wondering if anybody could advice me what other catalyst except of yeasts could I use?

Also i was wondering if somebody could explain mechanism for decomposition of h2o2 under alkali and acidic conditions?

the enzyme catalase decomposes H2O2. You can either use liquid catalase, or potatoes/liver for example, are a source of the enzyme. Other catalysts are manganese dioxide and silver.

The equation is:

2 H2O2 → 2 H2O + O2

It is faster in alkali conditions. Perhaps due to disassociation I don't know why, I've just been told to learn that.

Catalase is the enzyme in yeast. Other ones to do are iron oxide, lead oxide, manganese dioxide, potassium permanganate
